EHAT Metadata Discussion

This document outlines the structure and management of raw and processed data archives essential for simulation projects focused on historic event calibration. It covers methodologies for accessing and identifying metadata, including data type, unit, resolution, geographic location, and coordinate systems. The document emphasizes adopting existing standards like FGDC while considering custom implementations. Example requirements for MM5 rainfall metadata and GLOBUS-based data management schemes, including HDF5, are also discussed for effective data handling and model analysis.
